Riot if you plan on buffing GP further, do NOT give him more damage.
Currently sitting at a 48% winrate in Plat+ on Patch 9.6. My belief as a GP main is that he is in a balanced state when he's rocking a winrate around 48-50% so he is tiptoeing around attenton. If you are planning on giving him another look, please for the love of god do not add more damage into his kit. His ability to do damage has never been an issue or weak point. I strongly urge you to look into any of the following areas:
- Mana cost on Q changed to a flat 50 at all ranks. This acts as a mini buff to his early and a mini nerf to rank 4 and 5 Q mana cost.
- Base mana pool increase to 340 because GP is on the rather low end at 282 as an AD "Caster". Jayce, for example, has a base mana pool of 357.
- Some form of small refund mechanic on Q kills. The Q mana cost is 60 at Rank 1 so I recommend a flat 20 mana back on kill. That way it is still high impact to GP's mana pool if he chooses to use his Q for poke instead of farm.
Topic for another day but I also wholeheartedly believe that Klepto GP/Ezreal needs to die. Buffs will need to happen if they remove the ability to proc Klepto but playing GP with Klepto into a tank feels so bad for the opponent. I played against a Poppy and she was essentially my money pinata and also gave me a free skill point. It's just more frustration through RNG.
Feel free to discuss below whether you think these are good ideas and why, or bad ideas and what you would rather see changed (if changed)
